Preliminary

HD66750/1

(128 x 128-dot Graphics LCD Controller/Driver with

Four-grayscale Functions)

Rev 0.7

July 26th, 1999

Description

The HD66750/1, dot-matrix graphics LCD controller and driver LSI, displays 128-by-128-dot graphics

for four monochrome grayscales. Since the HD66750/1 incorporates bit-operation functions and a 16-bit

high-speed bus interface, it enables efficient data transfer and high-speed rewriting of data in the graphics

RAM. The following functions allow the user to easily see a variety of information: a smooth scroll

display function that fixed-displays a part of the graphics icons and perform verticalsmooth scrollingof the

remaining bit-map areas, a double-height display function, and a hardware-supported window cursor

display function.

The HD66750/1 has various functions to reduce the power consumption of an LCD system such as low-

voltage operation of 1.8 V min., a booster to generate maximum seven-times LCD drive voltage from the

supplied voltage, and voltage-followers to decrease the direct current flow in the LCD drive bleeder-

resistors. Combining these hardware functions with software functions, such as a partial display with

low-duty drive and standby and sleep modes, allows precise power control. The HD66750/1 is suitable

for any mid-sized or small portable battery-driven product requiring long-term drivingcapabilities, such as

digital cellular phones supporting a WWW browser, bidirectional pagers, and small PDAs.

Features
